FIELD: medicine.
SUBSTANCE: group of inventions refers to medical equipment, namely to a cardiac valve prosthesis to be attached to the interventricular septum. Proposed is a cardiac valve prosthesis attached to the interventricular septum, and a method of delivering and disconnecting the prosthesis of the cardiac valve attached to the interventricular septum. Prosthesis of cardiac valve comprises bearing valve frame and fixing device. Bearing valve carcass comprises valve attachment area and artificial valve. Artificial valve is fixedly connected with valve attachment area. Fixing device comprises fixing and supporting area and fixing element. One end of fixing and supporting area is connected to proximal part of valve suturing area. Other end of the fixing and supporting area is connected to the interventricular septum of the patient by means of a fixing element for supporting the prosthesis of the cardiac valve and limitation of the axial movement of the prosthesis of the cardiac valve. Method involves a stage of insertion of a delivery tube carrying a prosthetic cardiac valve into a ring of an atrioventricular valve through an invasive incision in the atrial wall. Method comprises a step of manipulating the delivery tube to detach the fixing means. Method comprises a step of manipulating a tube for delivering a disengagement region of the valve. Method involves a step of manipulating a delivery tube for inserting a fixing element into an interventricular patient's septum. Method includes a stage of extracting a tube for delivery from a human body.
EFFECT: technical result is elimination of problem of attachment technology from previous level of equipment, caused by radial expansion of patient's ring of patient's valve, and reduced effect on output circuit after disconnection of bearing frame and prevention of ring reduction of own valve.
